ShieldMobile

Really useful app for Shopify. I tried a few breadcrumb solutions before finding this one, and the customisation is much better than what I had before. It was also pretty quick to set up and get working on my store.

Very handy app for showing accessories on product pages. I like that you can choose which products go together instead of having the same recommendations everywhere. Makes a lot of sense for stores selling products with different add-ons.
